[Factors underlying gastroduodenal pathology in children].

Correlation analysis conducted in 106 children with chronic gastroduodenitis enabled us to distinguish leading factors in the onset of this disease, to estimate the strength of connection between clinicoanamnestic and laboratory-instrumental methods of investigation. A strong correlation was found in children with gastroduodenitis between changes of sialo-containing compounds, secretory IgA in the saliva and inflammation severity.
